NPK numbers are percent *by weight*. You can't just add numbers like that. If you want to know your aggregate NPK, you'd take the weight of each element in each amendment and divide by the total weight of the mix. Your math works if you use 100 g of everything, but that doesn't seem balanced...

Thanks! The end is near :)

Just under three months of growing I wanted to walk away. I let the EC drift to 2.6+ and the leaves got a little toasty. I started taking care of them two weeks later when they started smelling and showing trichs. Now they're at day 68 and just showed a few amber trichs. They're getting 2g/gal...

Week 3 of 12/12. Already seems like forever. Another 6-7 weeks to go. #1 is 55" tall, full of bud sites. Showing trichs. Looks like a keeper. #4 is 31" #2 is budding well. Fruity/floral. Fav smell of the bunch. 46" tall #6 is 51", lanky, and sparse

They seem to want 6 g/gal. Nice, shiny, olive leaves. I put them on 12 hrs and they're shooting up now. #4 is still 15" tall and the other three are 35" tall. Starting to flower heavy...like week 2 or 3 of flower. They're drinking around 2.5L per day. The light is at max - 480W. Temp is...

They're up to 5.5 g/gal of megacrop. They're turning forest green and shining up. The light is at 420W. They're drinking 2L per day now. #4 is short. #1 is berryish. The other two are very similar shape and skunkish smell. I killed a grapefruit male which Prof Sprout said is super duper rare...

They indicated sex at week 6. Still at 13 hrs light. Killed two males. The first was pretty skunky. The second was straight grapefruit. I considered using him for seed. Still at 4.5g/gal. It's a little hard to see leaf colour under 3000K light. Should probably go to 5g soon to encourage...

day 26 of veg with 13hr days. robust rapid growth stage. possibly bluing. responds well to topping. 4.5g/gal megacrop in a hempy bucket. Lush, fat, medium green leaves. Still not sure when to "flip" to 12/12. Dr Sprout says they double after flip, but that's probably from 18/6. Hawaii is...

Day 20. It's been a very slow start. No doubt 13 hr days didn't help. Dropped the light to 24". Even at the lowest power setting the plants didn't want to grow. Raised the light to 30" and they shot up overnight. Power has crept up to 267W. Fertigation is at 3.5g/gal of tap water, pH'd to 5.8...

Each tote takes a little under 3.5L solution to fill to the hole. Water wicks to the top. The seedlings are in amd will take a while to drink it up and spread their roots. LED are 36" above the perlite. I dimmed them to 199W and temp is holding at 82F. Temp will drop once the plants start...

All six seeds popped after 48 hours. I may just put them straight into their totes. The totes are 9" x 13" on the inside. I added 2.5L of water to get the height of the 1/4" holes and drilled all six totes. It worked out to 1.14" from the outside of the tote to the bottom of the hole. I've...

Picked up the shot glass in Amsterdam in 2007. Seems natural to use it here.

Back after a little eight year hiatus. I've wanted to do hempy since last year. I bought the chunky perlite, and put it aside for a quasi docbudhighbrix grow ... which was cursed. Some of my first times smoking in the mid '90s was pounding down food and really enjoying music with my...

Have you tried maxi grow throughout flowering? Its ratios are closer to Jacks, and more importantly (wrt black ash) it has much lower phosphorus than maxi bloom. pot sulfate would improve flavour. I want to try hempys with mega crop. fwiw, their new 2 part fertilizer is basically Jack's 321...

I took his class. lots of basic but good information. like they say, a black belt is a master of the basics. It's worth the $90 if you get even one gold nugget ... or maybe two. there's also the one on one. lots of info on riu ... and lots of sifting through pages of bad advice and opinions...

Oh for two... P2O5 has 43.7% P K2O has 83.0% K Say a 10-10-10 NPK in a solution gives 100-100-100 ppm N, P2O5, and K2O, respectively. We get 100-43.7-83 ppm N, P, and K. AN's full line gives something like 1-1-2 throughout the entire grow (if their labels are to be believed). Lucas formula...

The Aavid heatsink is $800 for single 12" piece :/ I also doubt the 2.12" tall fins conduct heat to the tips. I'd say heatsinks USA 7.28" extrusion works at least as well, for $31.56 usd per foot. The beauty of discreet LED is distributed heat footprint (COB concentrate heat in a relatively...

Good luck! Nice to see you've settled into your new home. The weather in ontario has been bipolar. veggies are suffering, but fruit trees are having a bumper harvest (weird!). I hope it's better in quebec.

nice trichome development. fap, fap, fap, fap, fap ;) have you stuck your nose right in there and smelled them? how does the house smell?

leaf shape is irrelevant with these highly hybridized plants. headband has a sativa high... also, that little girl is getting quite a bit less light than the taller ones. Raise her up on some blocks so that the tops are level. looking good ;) 5 weeks to go...
